Application filed January 26, 1917. Serial No. 144,781.

To all whom it-may concern: I

Be it known that I, ALBERT V. GUDE, Jn, acitizen of the United States,'residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Floor or Wall Grounds, of which the following is a specification.

This invention relates to floor or wall grounds of the general type disclosed in my co-pending application Serial No. 124,608 wherein the ground comprises a nail receiving block, a portion of adhesive wall-engaging material in which the block is partly embedded, and a metallic keying meansassociated with the under or inner face of said block and securely engaged and gripped by the adhesive material which also engages and grips said block.

The present invention consists more particularly in the novel construction, as hereinafter described and claimed, of the keying element of a floor or wall ound of the type stated and the novel relatlon of the said element to the nail receiving block; and the invention has. for its .principal objects to provide a keying element which can be easily, quickly and certainly applied to the nail receiving block, which requires no nails or other fastenings for its attachment to said block, and which may be made at a minimum of expense.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a sectional view showing the improved ground fitted to a wall or floor.

'Fig. 2 is a plan view showing the block and the keying elements of the ound.

' Fig. 3 is a sectional view of a slightly modified construction wherein the ground; is shown as fitted to a floor or wall.

Fi 4: is a bottom plan view of the block and eyi g elements of the construction shown in Fig. 3. p

Fi. 5' is a sectional view of a further construction, showing the ground as fitted toa wall or floor.

I Fig. 6 is a plan view of the block and keying elements of the construction shown in Fig, 5.;

Similar characters of reference designate corresponding parts throughout the several views.

The ground is shown as applied'to a wall or floor A and consists of the nail receiving block I, the portion of adhesive material 2,

such as plaster of Paris, in which said block 1s partly embedded and the keying elements 3.

In all cases the block and the keying eleunents are formed whereby the keying elements may be fitted to, and by virtue of their fitted relation, securely maintained upon, the block and the relation of the keying elements and the block is such that the adhesive material which grips the under face of the blotik will also securely grip and engage the keying elements. The keying element includes a bar which extends across the under face of the block and preferably contacts therewith, in which case, the said under face is provided with recesses across which the bar extends whereby portions of the bar will be wholly embedded in the adhesive material filling said recesses.

As shown in Fig. 1 the block has a dovetail cross-section and a keying element is arranged at each end thereof, the keying element comprising a frame, preferably of wire, andhaving a bar 4 which extends transversely across the end face of the block,

a bar 5 which extends transversely across the under face of the block, and angular terminal portions 6 which rest against the beveled sides of the block and connect the bars 4. and 5, the portions 6, of course, conforming to, or occupying planes parallel to the planes of, the said beveled sides against which they rest. Where the bar 5 contacts with the under face of the block as is preferred, said under face is provided with one or more recesses 7 which are preferably in the form of longitudinal grooves extending contmuously between the end faces of the block.

The fit of the keying elements upon the block is sufficiently close to insure the retention of said elements, against accidental displacement by frictional pressure.

The block with the keying elements fitted thereto in. the manner describedis then partly embedded in the plastic material applied to the wall and the said material engages the under face of the block and fills the groovesor recesses 7, thereby engaging over and securely gripping and retaining the keying elements.

In the modified construction shown in I Figs-3 and 4, the block is of substantially to conformably engage over the beveled sides of the block. In this modification the keying elements are not fitted against the ends of the block, as in Figs. 1 and 2, but may be arranged in any desired locations and in any desired number in'termedite said ends. construction shown in Fig. 3 may be employed in addition to and intermediate the keying elements of the construction shown in Figs. 1 and 2.

In the modification shown in Figs.5 and 6, the block does not have a dove-tail cross section, but, instead, is provided with laterally projecting base fianges 9; and the keying elements, which, as in the construction shown in Figs. 3 and 4, are composed of narrow bars or strips of sheet metal, are provided at their ends with angular terminal portions 10 to comformably engage over said flanges. Except for the variation in the form of the block, the modification shown in Figs. 5 and 6 is similar to that shown in Figs. 3 and 4.

It is to be noted that in each of the constructions described the keying elements are arranged in spaced relation whereby the nail receiving block and a portion of ad plastic material has free access to the underand side faces of the block for gripping engagement therewith, while at the same time, the said keying elements are, for substantial ortions of their length, embedded in and,

once, securely gripped and engaged by said material.

I claim as my invention- 1. In a floor or wall ground includingla sive material in which said block is embedded, said block being of greater width in its lower portion than in its upper portion and having its under face provided with recesses, a metallic keying element comprising-a relatively narrow bar extending across and adjacent the under face of said block and across the recesses thereof and provided with angular terminal portions which engage over the sides of said block and thereby hold said bar in position.

2. In a floor or wall ground including a nail receiving block and a portion of ad- If desired, keying elements of the hesive material in which said block is embedded, said block being of dove-tail crosssection and having its under face provided with recesses, a metallic keying element comprising a frame formed with a bar which extends transversely across and adjacent the end face of the block, a second bar which extends transversely across and adjacent the under face of the block and across the recesses thereof and angular terminal portions connecting said bars and fitted against the beveled sides of the block.

3. In a floor or wall ground including a nail receiving block and a portion of adhesive material in which said block is embedded, said block being of greater width in its lower portion than in its upper portion, a metallic keying element comprising a frame formed with a bar which extends transversely across and adjacent the end face of the block, a second bar which extends transversely across the under face of the block and is related thereto whereby it may be embedded in and engaged by the adhesive material engaging said under face and angular terminal portions connecting said bars and fitting against the sides of said block to thereby hold said frame in position.

4. In a floor or wall ground including a nail receiving block and a portion of adhesive material in which said block is embedded, said block being of greater width in its lower portion than in its upper portion, a metallic keying element comprising a relati.v.ely narrow bar which extends transversely across the under face of the block and is related thereto whereby it may be embedded in and engaged by the adhesive material engaging said under face, said bar being provided with angular terminal portions which engage over the sides of said blockand thereby hold said bar in position.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
